Talk:Cha 110913−773444

Luminosity

In the paper I got the values for luminosity from, they wrote Log L/L_☉ = -3.22. I wasn't sure whether Log was the natural log or Log₁₀, but the value I supplied (0.04) came from assuming they meant the natural log. If Log₁₀ was meant, then it should instead read 6 x 10^-4 L_☉.

Definitely log to base ten. Natural (base e) log would have been denoted ln. This was fixed in the article years ago. Modest Genius ^talk 23:14, 17 October 2012 (UTC)

Smallest

Since Cha 110913-773444 is NOT a brown dwarf according to this article, OTS 44 should still be the smallest (better:lightest) brown dwarf known, shouldn't it? --Roentgenium111 (talk) 19:57, 10 August 2010 (UTC)

Protoplanetary disk

Does anyone know how big this object's protoplanetary disk is? --JorisvS (talk) 16:21, 15 January 2013 (UTC)

Is that possible?

How is it possible to discover a Jupiter-size planet left in space, not illuminated by any sun? Does it radiate anything detectable? Thank you. - 92.100.170.169 (talk) 16:10, 6 November 2013 (UTC)

By the way: the link to the page at exoplanet.eu is broken. The NASA link, however, is working, and they appear to say it was actually a dark star by its physics, unless I am mistaken... - 92.100.170.169 (talk) 16:21, 6 November 2013 (UTC)

Sub-brown dwarfs can be detected by Infrared / thermal radiation. -- Kheider (talk) 16:43, 6 November 2013 (UTC)
